FWU: Pass client cookie to FWU_SMC_UPDATE_DONE
...
The current FWU_SMC_UPDATE_DONE implementation incorrectly passes
an unused framework cookie through to the 1st argument in the
platform function `bl1_plat_fwu_done`. The intent is to allow
the SMC caller to pass a cookie through to this function.
This patch fixes FWU_SMC_UPDATE_DONE to pass x1 from the caller
through to `bl1_plat_fwu_done`. The argument names are updated
for clarity.
Upstream platforms currently do not use this argument so no
impact is expected.

FWU: Remove image_id arg from FWU_SMC_IMAGE_RESUME
...
The current implementation of FWU_SMC_IMAGE_RESUME when called
from the normal world, uses the provided image_id argument to
determine which secure image to resume into. This implies that
the normal world has a choice of which secure image to resume
into when in fact it is only possible to resume into the
previously interrupted secure image.
This patch removes the argument, tightens up the pre-conditions
for the SMC and adds additional asserts.
The pre-conditions for FWU_SMC_SEC_IMAGE_DONE are also
tightened up.

FWU: Fix secure memory check in image auth
...
The implementation of FWU_SMC_IMAGE_AUTH performs a number of
pre-condition checks before authenticating the image. One of
these checks calls `bl1_plat_mem_check()` to ensure the image
source is mapped in when authenticating an image in place.
The framework incorrectly passes the security state of the
caller into this function instead of the security state of
the source image.
This patch corrects the defect. The defect would only
manifest itself for secure world callers authenticating
non-secure images in place, which is not done by current
upstream platforms.

Replace all SCP FW (BL0, BL3-0) references

This patch replaces all references to the SCP Firmware (BL0, BL30,

(https://github.com/ARM-software/arm-trusted-firmware/wiki):
BL0 --> SCP_BL1
BL30, BL3-0 --> SCP_BL2
bl30 --> scp_bl2
This change affects code, documentation, build system, tools and
platform ports that load SCP firmware. ARM plaforms have been
updated to the new porting API.
IMPORTANT: build option to specify the SCP FW image has changed:
BL30 --> SCP_BL2
IMPORTANT: This patch breaks compatibility for platforms that use BL2
to load SCP firmware. Affected platforms must be updated as follows:
BL30_IMAGE_ID --> SCP_BL2_IMAGE_ID
BL30_BASE --> SCP_BL2_BASE
bl2_plat_get_bl30_meminfo() --> bl2_plat_get_scp_bl2_meminfo()

Move up to mbed TLS 2.x
...
The mbed TLS library has introduced some changes in the API from
the 1.3.x to the 2.x releases. Using the 2.x releases requires
some changes to the crypto and transport modules.
This patch updates both modules to the mbed TLS 2.x API.
All references to the mbed TLS library in the code or documentation
have been updated to 'mbed TLS'. Old references to PolarSSL have
been updated to 'mbed TLS'.
User guide updated to use mbed TLS 2.2.0.
NOTE: moving up to mbed TLS 2.x from 1.3.x is not backward compatible.
Applying this patch will require an mbed TLS 2.x release to be used.
Also note that the mbed TLS license changed to Apache version 2.0.

The 'libssl-dev' package has been removed from the list of
prerequisite tools, as it is already referenced on the ARM Connected

De-feature PL011 UART driver to match generic UART spec
...
The Server Base System Architecture document (ARM-DEN-0029)
specifies a generic UART device. The programmer's view of this
generic UART is a subset of the ARM PL011 UART. However, the
current PL011 driver in Trusted Firmware uses some features
that are outside the generic UART specification.
This patch modifies the PL011 driver to exclude features outside
the SBSA generic UART specification by setting the boolean build
option 'PL011_GENERIC_UART=1'. Default value is 0 (use full
PL011 features).
User guide updated.
Fixes ARM-software/tf-issues#216

FWU: Add support for `fwu_fip` target

Firmware update feature needs a new FIP called `fwu_fip.bin` that
includes Secure(SCP_BL2U, BL2U) and Normal world(NS_BL2U) images
along with the FWU_CERT certificate in order for NS_BL1U to load
the images and help the Firmware update process to complete.
This patch adds the capability to support the new target `fwu_fip`
which includes above mentioned FWU images in the make files.
The new target of `fwu_fip` and its dependencies are included for
compilation only when `TRUSTED_BOARD_BOOT` is defined.

A new field in the extension structure will be used to indicate
that the extension is optional. In the case of an image hash
extension, this field will tell the tool that the hash should
be included in the certificate, but filled with zeros.

FWU: Add Generic Firmware Update framework support in BL1
...
Firmware update(a.k.a FWU) feature is part of the TBB architecture.
BL1 is responsible for carrying out the FWU process if platform
specific code detects that it is needed.
This patch adds support for FWU feature support in BL1 which is
included by enabling `TRUSTED_BOARD_BOOT` compile time flag.
This patch adds bl1_fwu.c which contains all the core operations
of FWU, which are; SMC handler, image copy, authentication, execution
and resumption. It also adds bl1.h introducing #defines for all
BL1 SMCs.
Following platform porting functions are introduced:
int bl1_plat_mem_check(uintptr_t mem_base, unsigned int mem_size,
unsigned int flags);
This function can be used to add platform specific memory checks
for the provided base/size for the given security state.
The weak definition will invoke `assert()` and return -ENOMEM.
__dead2 void bl1_plat_fwu_done(void *cookie, void *reserved);
This function can be used to initiate platform specific procedure
to mark completion of the FWU process.
The weak definition waits forever calling `wfi()`.
plat_bl1_common.c contains weak definitions for above functions.
FWU process starts when platform detects it and return the image_id
other than BL2_IMAGE_ID by using `bl1_plat_get_next_image_id()` in
`bl1_main()`.
NOTE: User MUST provide platform specific real definition for
bl1_plat_mem_check() in order to use it for Firmware update.

Add descriptor based image management support in BL1
...
As of now BL1 loads and execute BL2 based on hard coded information
provided in BL1. But due to addition of support for upcoming Firmware
Update feature, BL1 now require more flexible approach to load and
run different images using information provided by the platform.
This patch adds new mechanism to load and execute images based on
platform provided image id's. BL1 now queries the platform to fetch
the image id of the next image to be loaded and executed. In order
to achieve this, a new struct image_desc_t was added which holds the
information about images, such as: ep_info and image_info.
This patch introduces following platform porting functions:
unsigned int bl1_plat_get_next_image_id(void);
This is used to identify the next image to be loaded
and executed by BL1.
struct image_desc *bl1_plat_get_image_desc(unsigned int image_id);
This is used to retrieve the image_desc for given image_id.
void bl1_plat_set_ep_info(unsigned int image_id,
struct entry_point_info *ep_info);
This function allows platforms to update ep_info for given
image_id.
The plat_bl1_common.c file provides default weak implementations of
all above functions, the `bl1_plat_get_image_desc()` always return
BL2 image descriptor, the `bl1_plat_get_next_image_id()` always return
BL2 image ID and `bl1_plat_set_ep_info()` is empty and just returns.
These functions gets compiled into all BL1 platforms by default.
Platform setup in BL1, using `bl1_platform_setup()`, is now done
_after_ the initialization of authentication module. This change
provides the opportunity to use authentication while doing the
platform setup in BL1.
In order to store secure/non-secure context, BL31 uses percpu_data[]
to store context pointer for each core. In case of BL1 only the
primary CPU will be active hence percpu_data[] is not required to
store the context pointer.
This patch introduce bl1_cpu_context[] and bl1_cpu_context_ptr[] to
store the context and context pointers respectively. It also also
re-defines cm_get_context() and cm_set_context() for BL1 in
bl1/bl1_context_mgmt.c.
BL1 now follows the BL31 pattern of using SP_EL0 for the C runtime
environment, to support resuming execution from a previously saved
context.
NOTE: THE `bl1_plat_set_bl2_ep_info()` PLATFORM PORTING FUNCTION IS
NO LONGER CALLED BY BL1 COMMON CODE. PLATFORMS THAT OVERRIDE
THIS FUNCTION MAY NEED TO IMPLEMENT `bl1_plat_set_ep_info()`
INSTEAD TO MAINTAIN EXISTING BEHAVIOUR.
